For those unfamiliar with the Aero line of mufflers, they are a compact stainless steel muffler designed to be added to nearly any exhaust system that offers unrestricted airflow, while having unremarkable sound characteristics. The XL line of the AeroTurbines are considered their resonated version designed specifically to cancel out any in-cab drone that is typical of many aftermarket mufflers.

Built from T304 stainless steel inside and out, this muffler does not have any of the traditional packing found in many other mufflers that is known to breakdown over time, but rather uses a series of louvered baffles that are also designed to literally "suck" the exhaust away from the engine, even faster than a straight pipe, which results in lower exhaust gas temperatures.

Great Sound!!! Great Product!!!!
I put t this on a 2012 Ram 2500 Laramie 4X4 Diesel. The sound is great as mentioned above. It is a deeper sound than most exhaust components provide. I would recommend this product for any 6.7L Cummins if you want an aggressive sound with minimal cab noise.

100 Percent agree. We have ran those on many trucks here. Including a couple 6.7’s. They just plain work, and they look good for those that actually look under their truck occasionally. Glad you are liking yours! Next time you are looking for parts, look us up.

Great Aggressive Deep Sound
The Aero Turbine 4040XL is what I chose for my 2012 Ram 2500 Laramie 6.7L Cummins. It is somewhat mellow deep toned at idle, but aggressive and deep toned when put under a load. It has a little in cab resonation, but not enough to bother me. I would think twice about having the exhaust dumped behind it, as you would probably get an enormous amount of resonation in the cab. It is a GREAT sound!!!!

Thank you for the review. We have ran those mufflers on many trucks. They are probably our favorite. I agree on the dump, I have been in a 5.9 Common rail with that muffler that is dumped and it is a fair amount of drone. Still much much better then a straight pipe though. If you need anything else for your 6.7 let us know!

Straight Pipe to 4040XL
Bought this to help get rid of cab drone when driving the truck. Went from straight pipe from turbo to exhaust tip, to installing the 4040XL. This significantly reduced the raspy sound that the exhaust had, and made a much cleaner exhaust note. Drastically reduced the drone when under load at or near 2000 rpm. Install was fairly easy as existing exhaust had 6 1/2 years and 47,000 miles of use already. Installed with lap style clamps to make it a clean install. Would recommend the Aero exhaust lineup to anyone looking for a clean sound with little to no cab drone.

I put this on my 06 cummins 5.9l 6spd. i took the cat and factory muffler off and replaced it with this muffler. It is a great quality muffler and sounds amazing as a replacement for the factory muffler. No drone quiet while cruising and nice deep cummins growl when accelerating. Awesome product would definatley buy again.

Excellent finish, excellent product. On my 2012 Duramax it results in a very nice, deep mellow tone with zero drone at highway speeds.

Is this a slipp on and clamp over the four inch exhaust or a straight weld on muffler?

This will slip over 4"" exhaust, you may then clamp or weld it.

Where would be the proper position to install? front of exhaust, under cab, or just before the rear axle ??

That muffler is going to work best placed as far forward in the exhaust as possible.

I currently run a Gibson cat back setup on my 2005 5.9. The power gain is fine, but the drone is getting worse. Does the 4040XL have similar power gains and does anyone know if it is quieter than the Gibson setup? Also, are these legal in CA? Thanks!?

Not familiar with the Gibson system so I can't say if this would be louder then that muffler or not. It is typically a little quieter then a standard straight through performance muffler. The Aero muffler would flow just as well as a straight through muffler, you would see the same power gains there. The muffler alone should not have any issue being legal in CA on a Cat back system.-Sands
